EXTINGUISHING DEVICE FOR LAMPS. I

Specification of Letters Patent.

Iatcnted Sept. 25. 1906.

Original application filed November 2,1 905, Serial No. 2 8 6,5 9 7. Divided and this application filed March 24, 1 9 06. Serial 1%. 307,870.

To all whom it may concern:

Be it known that I, LOUIS ITISSIM, mechanician, a subject of the King of Great Britain,

residing at Mayfield, Rochford avenue, Vestthe cap of the burner which carries the chim ney or globe is so loosely mounted on the body of the burner that it will turn at once to operate the extinguishing device connected with it when the lamp receives a dangerous shock or is tilted to a dangerous angle, even if not actually upset. The cap is, however, held centrally in an efficient manner so long as the lamp is upright and the cap is positively connected to the extinguisher, so that this latter is thrown out of action immediately the lamp is erected after being upset.

In the accompanying drawings, forming part of this specification, Figure 1 is a sectional elevation showing the extinguishing device as applied to the top of the burnertube of an oil-lamp. Fig. 2 is a detail view illustrating a modification. Fig. 3 shows a slightly-modified form of construction, and

Figs. 4 and 5 are sectional elevations taken at right angles to one another and showing the arrangement according to this invention as adapted for use with a duplex lamp.

Referring first to Fig. 1, e is the body of the burner, suitably connected with the oillamp, and f is the wick-tube containing a burner-wick a. t is the upper part or cap of the lamp wherein the slot u is formed for the flame. The upper part t is separate from the lower part and is mounted thereon in such a way as to allow of a limited relative movement. In the example shown the two parts have V-shaped ridges formed around the same at y, while the edge of the upper part 15 has tongues bent over at 2 to engage under the edge of the rim 3 of the part c. w is the chimney, fitting into a suitable holder 2 on the part If. This chimney may of course be replaced by a globe or any other form of shade or flame tube used upon lamps. It will be seen that when the upper part or cap t is resting upon the lower part c the ridges y fitting together keep said parts in their proper relative positions. If, however, the lamp becomes tilted or thrown sidewise, the cap t can move relative to the part c within the limits allowed by the flanges 2. This movement is utilized for actuating the extinguisher. The extinguisher-plate 4 is mounted on arms 5, pivoted at 6 upon the wicktube f, and a tailpiece 7 is provided on said arm 5, the tailpiece having a pin 8, engaged by a forked projection 9, attached to the upper partt of the burner. With this device when the edge of the cap or upper part of the burner rises at any point the projecting piece 9 will also rise, lifting the pin 8 and so turning the arms 7 5 and bringing the extinguisher 4 over the top of the wick projecting from the wick-tube The movement allowed to the cap by the flanges 3 must be such that in whichever direction the cap tilts the end of the projecting arm 9 will rise sufficiently to operate the extinguisher. It will be seen, therefore, that the lamp will be extinguished at any time when the upper portion becomes tilted relative to the body portion of the lamp. Such tilting does not take place during the normal working or normal carrying of the lamp; but if the lamp begins to fall sidewise, owing to a shock or the like which it receives, the upper portion will tend to fall more quickly than the lower portion of the lamp, especially if there is a chimney upon the upper portion and the required tilting action will take place.

In the device shown in Fig. 2 two extinguishers 4 are provided, geared together in this case by toothed wheels 10, so that when the pin 8 on one of the extinguishers is raised by the device shown in Fig. 1 or by an equivalent device both extinguishing-pieces will move together over the wick until they occupy the position shown in Fig. 2. N ormally the extinguishers occupy theposition shown in dotted lines in Fig. 2.

Fig. 3 shows a small modification wherein the two extinguishers 4 arepivoted by tailpieces 14 at 21 on projecting arms 11, attached to the cap t, While the lower bent ends of the extinguishers 4 engage between ribs or projections 13 on the wick-tube f. When the cap tilts, the arms 11 rise, and as the extinguishers 4 are held at the bottom by the ribs 13 they are caused to flap together over the top of the wick. On replacing the cap in its normal position the extinguishers return also to their normal positions. The ridges y are shown of rounded or semicircular section in this case.

The arrangement for a duplex lamp is shown in Figs. 4 and 5. The actual. extinguisher 18 shown here is of the well-l nown duplex type and forms no part of the invention; but the operating device for the extin guisher comprises a bar 15, fixed in the tilting cap t, said bar having a slot 16 therein through which the cross-piece 17 of the extinguisher passes. The cap is also shown in this case as having its movement limited by headed pins 19, fixed in the part a and passing through slots 20 in the cap. In whatever direction the cap tilts it will be seen that the middle point of the bar 15 must rise to the same height, and the extinguisher will therefore be operated, no matter in what direction the lamp may be overturned.

What I claim is" 1. In an extinguishing device for lamps the combination with the burner-body of a loose burner-cap, means for centering the burner-cap on the body and allowing of a lim ited relative motion, an extinguisher and a positive mechanical connection between the cap and extinguisher such that immediately the burner is tilted to a dangerous angle the extinguisher will be operated, while when. the

burner is again. erected the extinguisher will be taken out of action.

2. In an extinguisher for lamps the combination of the burner-body, a cap separate from the burnerbody, coacting ridges on the cap and burner-body adapted to keep the latterin central position so long as the burner is upright, means limiting the relative movement of the cap on the burner-body, an extinguishing device, and a positive mechanical connection between the cap and extinguishing device.

3. In an extinguishing device for lamps the combination with the burner-body of a separate burner-cap, means for supporting the lampchimney on said cap, coacting ridges on the burnerbody and cap adapted to center the latter upon the former, means limiting the motion of the cap relatively to the burner, a pair of extinguishing-plates and positive mechanical connecting means between the cap and the extinguishing-plates, whereby said plates are operated to extinguish the flame when the cap tilts on the burner-body and are taken out of action when the cap is again erected.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

LOUIS NISSIM.
